---------------------------------
Summary: The tasks of CTAS on a partitioned table should be fine
grained
Key: TAJO-662
URL: https://issues.apache.org/jira/browse/TAJO-662
Project: Tajo
Issue Type: Improvement
Components: data shuffle
Reporter: Hyunsik Choi
Fix For: 1.0-incubating
CTAS on a partitioned table involves the shuffle phase. Unlike other shuffle
required operators, such as groupby and join, the tasks after shuffle can be
divided into fine grained tasks. In other words, intermediate data for the same
hash key can be processed on multiple nodes.
